In New Zealand, the most common cockroach species are the American cockroach and the German cockroach, although they’re not as prevalent as in some other parts of the world. These insects typically thrive in warmer areas and can be found in urban environments, especially in kitchens and basements.

American cockroach

Size: About 3-4 inches long.

Color: Reddish-brown with a yellowish margin on the pronotum (the shield-like covering behind the head).

Characteristics: They have long, slender antennae and can fly. They prefer warm, humid environments.

German cockroach

Size: About 1.1-2 inches long.

Color: Light brown to tan with two dark, parallel stripes running down the length of the pronotum.

Characteristics: Smaller and more common in kitchens and bathrooms. They reproduce quickly and prefer indoor environments.

Cockroach infestation prevention tips

Preventing cockroaches involves a combination of cleanliness, maintenance, and monitoring. Here are effective strategies to keep them at bay:

Maintain cleanliness

Regular Cleaning: Clean up spills and crumbs immediately. Sweep and mop floors frequently.

Dishes: Wash dishes promptly and don’t leave them in the sink overnight.

Food Storage: Store food in airtight containers and keep pantry items organized.

Eliminate hiding spots

Seal entry points: Check for cracks and gaps in walls, around pipes, and near doors and windows. Use caulk or weather stripping to seal these openings.

Remove clutter: Reduce clutter where cockroaches can hide, such as stacks of newspapers, cardboard, and unused items.
